' Be. it known that'I', WILLIAM L. FIN NE, a

citizen of the United "States, residin at Elizabeth in tlie lcoun ty{of Union and tate of New Je1'sey,"fhaveinvented certain new and useful Improvements in 'Condenser= of which the following isa full, clear,

Coils,

' and enact specifibationg in the claims at the end of the description.

In the accompanying drawings; wherein- This invention; relates to condenser coils, and has for its object to provide an improved and simplified form ofjoint especially de[ signed for thepipes of'condenser coils.

In the operation of. condensers,' gas is passed through pipe coils, and as the gas condenses the liquid runs down the pipes on both the inside and outside surfaces thereof. 3

It is importantto provide a joint between the sections of the pi e coils which w-ill,pre' vent the gas from lea ring out and the liquid which runs down the outside of the pipes from entering the coils. The presentinvention provides such a joint which isalso composed'of a minimum-number of parts, all of which are formed integral with the pipes, so that it is unnecessary to employ any separate parts which are become lost. n

The invention will be first hereinafter de- -seribed in connection with the accompanying:

drawings, which constitute part of this sp'eciiication' and then more specifically [defined similar reference characters are used to des-.

ignate corresponding parts throughout th several views; v r
